AUTOMATIC GAS-STOVE I..IGH'1111131k Application led October 31, 1927.Serial No. 230,011.

This invention relates to automatic igniting devices and pertainsparticularly to an automatic ignitor designed for use in connection withgas stove burners.

The primary objects of the present invention is to provide, in a manneras herein after' set forth, a device designed to ignite a gas burner orrsimilar g'as fixture, automatically and simultaneously with the turningonof the control valve.

Another object of the invention is to provide, in a. manner ashereinafter set forth, an automatic ignitor which, when the gas fixturein association with which it is used is in use, will act as a pilot tore-light the fixture in the event that the same is accidently put out.

The invention has for another object the provision of an automaticlighting device for use in association with gas fixtures, wherein a gasjet is ignited independently of the lixture and acts to light thefixture when the control valve thereof is turned on, the lighting` jetcontinuing to burn while the fixture is in use and acting in the eventof accidental extinguishment of the fixture, to re-light the same, thejet being so located and protected that the possibility of it beingextinguished, is very slight.

A further object of the invention is to provide an automatic lightingmeans for gas fixtures of the character described, which will be ofsimple but strong and durable construction requiring little or noattention, and having a minimum of moving parts to get out of order.

Numerous other objects and advantages of the present invention willbecome apparent as the description of the same proceeds and4 theinvention will be best understood from a consideration of the followingdetailedv description taken in connection with the accompanying drawingsforming a par-t of this specification, with the understanding, however,that the invention is not confined to any strict conformity with theshowing of the drawing but may be changed or modified so long as suchchanges or modifications mark no material departure from the salientfeatures of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a top plan view of the invention described.

Figure 2 is a side elevational view of the structure embodying thepresent invention.

Figure 3 is a section taken substantially upon the line 3-3 of Figure 1.

Figure 4 is a plan view of the main portion of the invention showing thesame in one position assumed in the first part of the operative movementof the device.

Figure 5 is a transverse section taken substantially upon the line 5 5of Figure 1.

Figure 6 is a section taken substantially upon the line (iL-6 of Figure1.

Referring now to the drawings in detail wherein like numerals ofreference indicate corresponding parts throughout the several views, thenumeral 1 indicates a portion of a gas manifold from which one 0r moregas fixtures of the type indicated by the numeral 2 are fed. The fixture2 here shown is conventionally illustrated and symbolizes the usual gasrange burner which has the feed pipe 3 leading thereto the outer end ofwhich. pipe is bell shaped as indicated at 4, in the usual manner. Avalve body indicated generally by the numeral 5 is tapped in themanifold body 1 having the coupling 6 leading therefrom and the handle 7con trolling the usual plug body 8, the lower end of which projectsbeyond the valve body 5 as indicated at 9, which end or stem. 9 issurrounded by the spring 10 which normally acts to draw thev plug 8 intothe valve body and thus maintain the same leak-proof. For use inconnection with the structure embodying the present invention, the stem9 has secured thereto the arm 11 which projects rearwardly at an anglewith respect to the valve control handle 7. The oificeof this arm willbe described more fully hereinafter.

Connected to the valve 5 by means of the coupling 6 is a gas supply line12 which has the two branches 18 and 14, the branch 13 constituting thepilot supply pipe while the branch 14 extends into and terminates in theburner feed pipe bell 4 as clearly shown in Figure 1. The pilot lightsupply pipe 13, as shown in Figure 1 branches laterally intermediate itsends and has the free end portion 15 thereof arranged in a plane abovethe pipe 14 and substantially parallel therewith terminatingsubstantialy midway between the burner .2 and the control valve 5, inthe pilot tip 16.

Resting upon and extending longitudinally of the burner feed pipe 3 is asupporting block of generally elongated rectangular contour, indicatedgenerally by numeral 17.

This block is provided at each end with the laterally projecting ears 18each of which is provided with the depending portion 19 which extendsdownwardly on opposite sides of the pipe 3 as is clearly shown inFigures 3 and 5. Each of these depending portions 19 of the ears 18 hasthe longitudinally ei;- tending bore 2() formed in the lower end toreceive the shanks of the screws 21 which pass through the clamp plates22 and extends across the underside of the pipe 3 as shown.

At the rear of the block 17 is formed the laterally extending aperturedbearing 23 through which the straight portion of the pilot pipe 13extends, this pipe beingl clamped in position in the bearing 23' by thebinding screw 24. The upper portion of the block 17 is formed to providethe tubularrhousing 25- the rear portion of which is internally threadedas at 26 to receive the tension nut 27. The forward portion of thehousing body 25 snugly receives a pyrophoric pencil 28 against the rearend of which the tension nut 27 forces the spring 29 which is housed inthe rear threaded pon tion of the housing, the forward end bearingagainst the rear end of the pencil while the rear end-thereof is pressedupon by the tension nut27 as clearly shown in Figure 6.

Upon theV forward end of the body 11 there is mounted in alignment withthe housing 27, the ratchet wheel or striker 30 which as shown rotatesabout the vertical aXis of the pin 31. This ratchet 30 bears against theforward end of the pencil 28 which is in alignment transversely of thestructure with the pilot tip 16 so that sparks struck from the pencilwill pass the end of the pilot 'tip and ignite gas issuing therefrom.

Surrounding the upper end of the pivot pin 31 is a sleeve 32 which hasextending therefrom an integral arm 33, the sleeve at the opposite sidebeing provided with a longitudinally extending rib 34 for the purposehereinafter to be pointed out. The sleeve 32 and the ratchet 30 aremounted to turn together in a clockwise direction only about the pin 31.

Pivotally att-ached as at 35 to the free end of the arm 33 is a dog 36having the eX- tended portion 37 to the outer end of which is pivotallyattached as at 38 one end of the pull link 39, the other end of thislink eX- tending to a point adjacent the valve 5 where it is pivotallyattached as at l() to the arm 11 which is mounted to rotate with the'valve plug 8.

Overlying the pilot tip or vnozzle 16 and the ratchet wheel and sleeves3G and 82 is a cover plate l1 which is primarily intended to protect themechanism from any substance which may be spilled over the gas burner 2.

A portion of the edge portion of the cover plate 31 is provided with adepending flange 42 to which is secured one end of the spring i3, thefree end of this spring extending in wardly and having a groove 4Aformed thereacross in which the rib 3ft of the sleeve 32 normallyengages, preventing the sleeve from turning until suiiicient power is:tp-

'plied thereto to force the rib to slip out of the groove 14 in thespring.

The cover plate 41 has the pivot pin 31 passed therethrough and is thusheld in position by this pin and in addition a securing screw 45 ispassed through the plate at one side and `into the fork 46 formed fromthe side of the housing 25.

From the foregoing description it will be readily seen that when the gasvalve handle 7 is turned the supply line will be half opened before thedog 36 swings to the position shown in Figure 4- where it engages theratchet 30. Further turning of the valve handle 7' will swing the dogtlirough the niedium of the connecting links 39, and due to itsengagement with the ratchet 30 will cause the arm 33 and the ratchet toturn also, the rib 3d breaking away from the spring 43 as will bereadily understood thus causing the teeth of the ratchet wheel 3() toscrape across the pencil 28 and throw sparks across the point of thepilot tip 16 to ignite the gas issuing therefrom. 'lhe jet of llamewhich will be projected from the tip 16 will extend to the burner 2 andthus ignite the gas Howing therefrom and, as will be readily understood,if the gas burning at the burner 2 is accidently extinguished the pilotwill continue to burn and will immediately relight the burner. Theclosing of the valve 5 will return the arm 33 and dog 36 to originalposition as shown in Figure 1 ready for further use.

I-Iaving thus described my invention what I claim is:

1. In combination, a gas burning element,
